Definitions

  • LEDs Light emitting diodes
  • LEDs can be used as light sources for data transmission, as described in U.S. Patent Nos. 6,879,263 and 7,046,160, the entire contents of each being expressly incorporated herein by reference.
  • LEDs have many advantages over conventional light sources, such as incandescent and fluorescent lighting, for example.
  • One important advantage is their quick response to "ON” and “OFF” signals, as compared to the longer warm-up and response times associated with fluorescent lighting, for example.
  • Another important advantage is their efficiency in producing light, as measured in lumens per watt.
  • More buildings are incorporating wireless networks within the building, the networks which are intended to reduce the need for wiring alterations and additions practiced heretofore.
  • these wireless networks are not contained within the wails of a building, and so they are subject to a number of limitations.
  • One of these is the lack of specific localization of a signal and device.
  • RP Radio-Frequency
  • a clock with an optical transceiver limits or directs visible light by known optical components such as lenses and reflectors to selectively narrow the radiant transmission energy, as opposed to omni-directional transmissions.
  • a clock with an optical transceiver reduces interference with existing communication systems like those that are common today.
  • a clock with an optical transceiver facilitates and simplifies set-up, testing, troubleshooting and the like with respect to various facility systems, hi some embodiments of the present invention a clock with an optical transceiver generates relatively high energy outputs using the preferred visible light communications channel, since the human eye is adapted and well-protected against damage from visible light. In contrast, many invisible transmission techniques such as Ultraviolet (UV) or Infra-Red (IR) systems have much potential for harm.
  • UV Ultraviolet
  • IR Infra-Red
  • FIG. 7 illustrates by isometric projected view a second embodiment of a slave clock combined with optical transmitter and receiver in accord with the teachings of the present invention.
  • Optical detector 3103 may either be a broad spectrum detector or alternatively color-filtered or sensitive to only a single color. Detector 3103 will be any of the many known in the art, the particular selection which will be determined by well- known considerations such as sensitivity, reliability, availability, cost and other considerations.
  • Bandwidth may be limited by existing clock synchronization wiring, but should still be able to provide enough to additionally incorporate video signals from at least one user, such as a teacher in a classroom.
  • all types of data or information may be carried through the preferred communications systems illustrated in the Figures, including but not limited to telephone signals, television signals, Internet connections, building maintenance wiring such as thermostats, fire alarms, motion detectors, and any other electrical or electronic apparatus existing or appearing within the room or space.
  • building need to be wired only for power and synchronized clocks, saving a huge infrastructure of other wires and fixtures and in turn saving a great deal of money.
  • UV Ultraviolet
  • IR Infra-Red

Abstract

La présente invention concerne un système de voyants lumineux DEL et de communication en communication avec un module à bande large sur un système de communication de ligne d'alimentation. Ce système de voyants DEL et de communication comprend au moins un émetteur-récepteur optique. Cet émetteur-récepteur optique comprend un cadre de voyants comportant une pluralité de diodes émettrices de lumières et au moins un photodétecteur qui leur est joint ainsi qu'un processeur. Ce processeur est en communication avec les diodes émettrices de lumière et avec le ou les photodétecteurs. Le processeur est construit et arrangé pour générer un signal de communication. Le ou les émetteurs-récepteurs optiques sont engagés à une horloge et celle-ci est en communication avec le module à bande large sur un système de communication de ligne d'alimentation.
